LANC expands its product range of reverse osmosis membranes

The new Lewabrane HP (High Performance) series of membranes for brackish water treatment
The new product line has an average desalination rate of 99.7% (conditions of 2000 ppm NaCl; 225 psi) and high permeability, a further development of the highly cross-linked polyamide membrane introduced by LANC in 2012. Controlling polyamide crosslinking during the production process creates a small effective "pore diameter" for high solute retention, regardless of the charge charge on the solute. "By optimizing the process, you can increase the volume of the product without affecting the quality of
the
. As a result, high retention rates can be achieved at high pass rates, even when the water intake parameters, such as pH or salinity, are constantly changing," said Dr. Jens Lipinzki, Head of Membrane Product Marketing at LANC Liquid Purification Technology.
Lansheng will present the newly developed Lewabrane HP membrane element for the first time at a membrane technology conference and exhibition organized by AMTA and the American Water Industry Association (AWWA) from February 25 to 28, 2019 in New Orleans, Louisiana, USA.to maintain high efficiency even under changing conditions
reverse osmosis technology for desalination and purification of water, which is rapidly evolving in industrial, municipal and wastewater reuse applications where parameters can change rapidly. Lewabrane HP membrane elements ensure high retention of important elemental ions, even when temperature and acidity vary. In different applications, different kinds of elements are considered important. Silicon is an important element in boiler water, while an important element in wastewater applications is nitrates or organic matter.
" high desalination rates combined with energy efficiency are useful in multiple industries, especially when combining other separation processes such as ion exchange in reverse osmosis process designs. The advantage is that the operating pressure is lower and the retention rate is higher, which makes the ion exchanger cycle longer. Dr Lipnizki added. Therefore, typical applications are combined processes such as boiler water production for power generation, zero liquid discharge process (ZLD) or ultra-pure water production. However, the product can also be used in innovative processes such as closed-circuit reverse osmosis (CCRO), where the water supply component changes with each cycle, and continuous retention is an important advantage of the new Lewabrane HP product.
addition, LewaPlus is an engineering tool developed by LANC to facilitate the design of water treatment facilities easily and reliably. The software can be used to design ion exchange and reverse osmosis membrane devices and combination systems respectively. It brings together LANC's extensive knowledge and experience in both technologies to provide plant designers with advice on how best to configure membrane components as needed. The latest version 2.0.9 software already includes the newly developed Lewabrane HP family of products.
